Abstract
La présente invention concerne un appareil à arbre de liaison comprenant un axe de roue (30), un manchon d'axe (31), une cage de roulement à billes (32), des billes (33), un arrêtoir à bille (34), un manchon d'arrêt de rotation d'arrêtoir à bille (35). Des trous de réception de cage de roulement à billes (62) sont disposés au niveau de l'une ou l'autre extrémité du manchon d'axe (31). Un trou d'arrêt de rotation d'arrêtoir à bille (53) est prévu sur l'arrêtoir à bille (34). Se trouve disposée sur le trou d'arrêt de rotation d'arrêtoir à bille (53) et/ou le manchon d'arrêt de rotation d'arrêtoir à bille (35), une structure d'extraction de manchon d'arrêt de rotation d'arrêtoir à bille pour le serrage et l'extraction du manchon d'arrêt de rotation d'arrêtoir à bille (35) monté sur l'extérieur d'une partie filetée externe d'un arrêtoir à bille de l'axe de roue (30) et à l'intérieur du trou d'arrêt de rotation d'arrêtoir à bille (53). Les billes (33) sont montées à l'intérieur de la cage de roulement à billes (32). La partie externe filetée de l'arrêtoir à bille d'un arbre de liaison (2) traverse le manchon d'axe. La cage de roulement à billes montée au niveau de l'extrémité du manchon d'axe est reliée à un filetage de l'arrêtoir à bille. Le manchon d'arrêt de rotation est monté à l'intérieur du trou d'arrêt de rotation d'arrêtoir à bille (53). Dans le manchon d'arrêt de rotation d'arrêtoir à bille, une partie d'arrêt de rotation (57) s'adapte à une partie d'arrêt de rotation d'arrêtoir à bille (54) pour restreindre la rotation du manchon d'arrêt de rotation d'arrêtoir à bille par rapport à l'axe de roue (30). La partie d'arrêt de rotation de l'arrêtoir à bille (54) s'adapte à une partie d'arrêt de rotation externe (56) du manchon d'arrêt de rotation d'arrêtoir à bille pour restreindre la rotation de l'arrêtoir à bille (34) par rapport au manchon d'arrêt de rotation d'arrêtoir à bille (35). L'arrêtoir à bille (34) est monté de manière non rotative avec l'axe de roue (30). Ceci est avantageux du fait que le manchon d'arrêt de rotation d'arrêtoir à bille (35) peut être extrait de manière pratique, rapide et fiable à partir de la partie d'arrêt de rotation d'arrêtoir à bille (54), tandis que l'arrêtoir à bille (34) et l'arbre de liaison (2) ne se décalent pas dans le sens inverse.
